The One File I Created for Every Programming Language (10+ Years)
Throughout my career, while exploring different programming languages, I realized that having a quick reference was essential for refreshing my memory on the fly. So I developed a habit: for every new language I learned, I’d build a reference file (like python_reference.py) that documented everything from basic syntax to advanced features. Now, a decade later, these files have become my go-to resource. They’ve helped me study for interviews, revisit old projects after years, and now, in the AI era where generating code in unfamiliar languages is more common than ever, I think they’re more…
In plain words
A collection of reference files documenting syntax and features for 10+ programming languages, built over a decade. Designed for developers who need to quickly refresh their memory on language basics and advanced concepts, study for technical interviews, or understand code generated by AI tools in unfamiliar languages. Each reference file provides concise, practical examples without requiring extensive course materials, making it useful for developers picking up new languages or returning to old projects.

Throughout my career, while exploring different programming languages, I realized that having a quick reference was essential for refreshing my memory on the fly. So I developed a habit: for every new language I learned, I’d build a reference file (like python_reference.py) that documented everything from basic syntax to advanced features. Now, a decade later, these files have become my go-to resource. They’ve helped me study for interviews, revisit old projects after years, and now, in the AI era where generating code in unfamiliar languages is more common than ever, I think they’re more relevant than ever. A concise, straight to the point reference can be the difference between "it works" and "I actually understand why it works." I believe these references will be especially helpful for developers looking to pick up a new language quickly, without having to go through extensive courses or tutorials. I've updated most of the references, added some new ones, and made them open source. I've also put together a website where you can find them all: https://referencecollection.com/ Github Repo: https://github.com/DisclosedCode/referencecollection.com I’d love to hear your thoughts, and feel free to contribute if you have ideas or improvements! <3

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…

I was at FB/Meta from late 2013 to early 2023, mostly working in the compiler/runtime spaces. I got hit in the spring 2023 layoff wave. I immediately started making games in my newfound free time (a lifelong interest, and I even worked in AA(A?) back ca. ~2000), and in October 2023 I stumbled upon the idea of a roguelike pachinko/plinko game inspired by Luck Be A Landlord. Things snowballed quickly, I started talking to publishers, then worked like crazy through all of 2024, almost the hardest I've ever worked in my career, and launched the game in December 2024. It's sold…

i wanted to change the habit of reaching for my phone in the morning and doomscrolling away an hour so i built an app to help me. now i have to literally touch grass before accessing my most distracting apps the app is built in swiftui, uses the screen time apis provided by apple and google vision to recognise grass or not i'd love to get your thoughts on the concept.
